Reporter: One big difference r prince william is now changing diapers or nappies as they call them in the uk. At the moment I'd like to sleep more and maybe not change as many nappies. He's a little bit of a rascal. He reminds me of my brother or me when I was younger. Reporter: He expresses his desire to be a hands on father, from putting the car seat in place -- I had to practice, I really did. I was terrified that it was going to fall off or the door wasn't going to close properly. Reporter: To his decision to drive his wife and son from the hospital. If I can do it myself I want to do it myself. Reporter: Contrary to this picture, he says his son, just a few days shy of a month old, isn't much of a sleeper. He's a fighter.
